Santa Rosa Gardens

A long-flowering cultivar, Black Adder boasts numerous bottlebrush flowers of vivid blue flowers which emerge from darker purple buds. It starts to bloom in midsummer and continues until early fall. Use this perennial to provide color in the garden late in the season when many other plants are finished. Black Adder's foliage smells distinctly like black licorice when crushed, thus its common name, Anise Hyssop.  Suitable for gardens in the Coastal South, and an excellent choice for container gardening!

Agastache should be planted in full sun and slightly alkaline soil. The most critical factor is good drainage. This plant will NOT tolerate wet soil, especially in winter. When planting, put a thick layer of gravel in the bottom of the hole and then mix more in with the filler soil. Native to the southwest US and Mexico, it is naturally heat and drought tolerant.
